论文摘要
二维的DILATON重力模型，包括jackiw- teitelboim模型及其变形，是泊松西格玛模型的特定情况。目标空间差异形态映射一个泊松sigma模型。我们建议在不同的Dilaton重力模型中使用这些差异性来鉴定渐近条件，边界作用和渐近对称性。例如，我们在jackiw- teitelboim重力中使用渐近条件来在一类渐近的rindler模型中构建Virasoro对称性的渐近问题。我们表明，该方法可以应用于一对宽的DILATON重力，并讨论可能的概括。
The dilaton gravity models in two dimensions, including the Jackiw--Teitelboim model and its deformations, are particular cases of Poisson sigma models. Target space diffeomorphisms map one Poisson sigma model to another. We propose to use these diffsomorphisms to identify asymptotic conditions, boundary actions, and asymptotic symmetries in distinct dilaton gravity models. As an example, we use the asymptotic conditions in Jackiw--Teitelboim gravity to construct an asymptotic problem with Virasoro symmetry in a class of asymptotically Rindler models. We show, that the method can be applied to a wide class of pairs of dilaton gravities and discuss possible generalizations.
